Ammonia, NH3, can be made by reacting nitrogen with hydrogen.

N2 + 3H2 = 2NH3

How many moles of NH3 can be made if 7.5 moles of H2 react with enough N2?

Please help!

Your balanced equation indicates that for each mole of hydrogen, 2/3 mole of ammonia is made.

What is 2/3 of 7.5moles

5nh3=2.5n2+7.5h2

To determine the number of moles of NH3 that can be made, you will need to first identify the mole ratio between H2 and NH3 based on the balanced chemical equation.

According to the balanced chemical equation:
N2 + 3H2 = 2NH3

The mole ratio between H2 and NH3 is 3:2. This means that for every 3 moles of H2, 2 moles of NH3 are produced.

Given that you have 7.5 moles of H2, you can use the mole ratio to calculate the number of moles of NH3 produced.

Number of moles of NH3 = (Number of moles of H2) * (Mole ratio of NH3 to H2)

Number of moles of NH3 = 7.5 moles H2 * (2 moles NH3 / 3 moles H2)

Number of moles of NH3 = (7.5 moles * 2) / 3

Number of moles of NH3 = 5 moles

Therefore, 7.5 moles of H2 reacting with enough N2 will produce 5 moles of NH3.

To determine the number of moles of NH3 that can be made, we need to use the balanced chemical equation:

N2 + 3H2 = 2NH3

This equation shows that for every 3 moles of H2, we can produce 2 moles of NH3.

Since we have 7.5 moles of H2, we can calculate the moles of NH3 as follows:

(7.5 moles H2) * (2 moles NH3 / 3 moles H2)

This allows us to cancel out the units of moles H2, leaving us with the moles of NH3.

Calculating this expression will give us the answer:

7.5 moles H2 * (2 moles NH3 / 3 moles H2) = 5 moles NH3

Therefore, 5 moles of NH3 can be made if 7.5 moles of H2 react with enough N2.
